Parametric sunshade
« on: May 19, 2020, 09:09:31 PM »
Hello,
I would like to create sunshade that adapt to the windows "hole", with random parameters by spline (example fig 01) :
- number of blades (seems ok)
- angle of blades (seems ok)
- padding of blades (space between them)

Until now, I just created a working A2S generator with clipping spline and Extend to XY area (fig 02).

I'm facing several difficulty that I couldn't resolve :
- my segment deform while rotating
- dont know of to fill an entire spline with one type not deforming

I try to have a look on the windows shade tutorial, but couldn't solve...

Thanks ! :)

JG

Hi
I created a Macro for you. Maybe you could find it useful. Let me know if you need something more.
(to avoid issues, please set your Blade orientation/pivot to match my initial box/blade)
Best Regards

# Itoo

When I was creating this Macro I notice Transform operator is not acting as a NULL. Can you please check it for me or I`m missing something...
Thanks

Glad to help.
Please download and use BLINDS.max file.
BLINDS_NULL_ISSUE.max is just for Itoo guys to check something.

Well... this is wonderfull !

I wish I can produce this... I just use RC basically, this is really something else. Bravo !

Well, if you would like to improve it, it can be nice to have :
- % of totally close or open
- cable system on each extremities that stop to the last blade.

But like this it's already super nice !

Thank you guys, this is really cool :)

Hi
- % of totally close or open - DONE
Since now you can control opening by percentage (0=all close, 100=all open) there is no need for Open/Close checkbox but I decide to keep it and move it at the bottom (named Close All). Also added Rotation Off   ;)

 - cable system on each extremities that stop to the last blade
If you are referring to avoid overlapping/disappearing blinds when Max Open value is set to/near 100% - DONE.
Now you can set Open% value to 100 and Blinds will not overlap/disappear (blind will stack to the zero-padding).
You will notice for openings above 80% rotations will automatically go towards the horizontal position until the full horizontal at 100%.

note:
Since Randomise Operator (used to mix open/close) can`t be affected by some Seed operator inside Style Editor you will have to use General Random Seed for positioning Fully Closed Blinds.
 
Best Regards

No its more about having one cable at each extremities, that handle the blades. And this cable length adapt to the position of the last blade :

It can be nice also to have a stack of blade at the end, like in the link below.

Ah, yes...
Well, I guess it would be possible but it requires a lot more calculations. It will be good if you can provide some completed model example so I have something to start with.
I can`t promise anything because this  Macro was just about 1 hour of work/testing. The complete system probably will require a lot of time to generate although it is a challenge.
So, when I`ll find some time from the deadline project I will definitely take a look.

Yes I can imagine, the previous version is already very very very helpful !
Thank you !

By complete model, do you mean a RC one ? Or a .max still one ?

Something like this: https://3dsky.org/3dmodels/show/jalousie_1
But I can find it on the web, this is not a big issue.
As for the stack of blades, there are some easy/fake option to attach pre modeled stacks at the end or to go with real stacking behavior which will require heavy computing and participation of Itoo Gurus   .
